Photos of sketch attached showing connection assembly at top side. Basically 2 HSS “arms” extend out from the ladder structure and are welded with a vertical plate connection to a base plate anchored to the...
My answer there is that I don't yet have a reason that modification can't be done at the top. Spacing near the existing anchors is somewhat tight, and rebar layout in the slab is closely spaced. But I'm starting to think you may be right and that the best answer is to work there rather than @...
Yes, mostly, but the rubber foot part is something to consider.
That's a good point about the vertical seismic force decreasing friction reliance. Will explore the code more on this.
Thanks!
No connection can be made to the floor because this stainless steel liner/floor can only be modified/connected to at certain locations where embedded plates exist, which are not here.
The rubber soled foot may be a good idea bc the coeff of friction would improve vs steel on steel. You're...
RE:retired13....There are a couple lateral supports coming off the ladder now that provide friction resistance (St steel on St steel) along the wall. The anchor/top connection part of your solution is also something i'm considering. Space is tight where the original anchors are, but may be...
Anyone worked on a base plate type design where you can't fix the base and must rely on friction to maintain some stability?
I'm working on a design to modify an existing ladder mounted at the top of a concrete deck, extending down about 25 ft to the floor at the base of the ladder. The problem...
